Surveys were conducted at low and high tide at each site twice. At each site, three observation points were selected to provide three complementary views of the zone. These observation points covered the marsh platform, creekside marsh edge, and upland-side marsh edge. At each of the three points, observers performed a 10 minute scan using binoculars. During the scan, they noted the following about any bird observed: species, activity (flying, standing in marsh, standing in creek, hunting, nesting), and it’s location within an area (upland edge, midmarsh, creekbank, mudflat, in creek). Observers endeavoured to only count each individual once during a 10 minute scan.
